Sky box? in general ?(Collision Engine)

"The level must be surrounded by a hollowed sky block for collisions to work."

is that still necessary? What does it mean? Must be surrounded by hollowed block with a sky texture? Is a hollowed block necessary additional, if you have a sky cube?

Can someone explain me the thing with collision, please

I´ve got Version A6.60

thanks for some explanation.

make a block, scale it to your needed size and apply a sky texture, that's it.

A skycube just defined in the script does not have any collision, so it is better if you use the "block-method"

i design a space level without a skycube and i'm not even receiving a "level leaking" message, nor do i have problems with collision. but i remember an issue with physics collision in absence of a skycube.

yeah, it's just for the physic-engine

thank you both of you
